C# insert data from datatable to SQL Server database

I have tried nearly every solution on this website, but I can't solve this problem. I have data that has been retrieved from a database through an ODBC connection. The data is there. It will go into a Data Grid View just fine, but I can't get this data to go into my local SQL database. Please tell me what I'm doing wrong.

public partial class frmNorth : Form
{
// variables for the connections
private OdbcConnection epnConnection = new OdbcConnection();
private SqlConnection tempDbConnection = new SqlConnection();
public frmNorth()
{
InitializeComponent();
// This is for the ePN DB
epnConnection.ConnectionString = @"Dsn=ePN; uid=username; pwd=myPa$$Word";
// This is for the local DB
tempDbConnection.ConnectionString = @"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\TempDB.mdf;Integrated Security=True";
}
private void btnLoadData_Click(object sender, EventArgs e)
{
try
{
//===This part works just fine===============================================================
epnConnection.Open();
string epnQuery = "SELECT FNCL_SPLIT_REC_ID, PROJ_ID, SALES_SRC_PRC " +
"FROM PROJ_FNCL_SPLIT " +
"WHERE PROJ_ID=" + textBox1.Text + "";
OdbcCommand epnCommand = new OdbcCommand(epnQuery, epnConnection);
epnCommand.CommandTimeout = 0;

//This connects the data to the data table
OdbcDataAdapter da = new OdbcDataAdapter(epnCommand);
DataTable dt = new DataTable();
da.Fill(dt);
dataGridView1.DataSource = dt;
//===========================================================================================


//======The part below is the part that wont work. The data wont go into the SQL database====
tempDbConnection.Open();
string tempSql = "";
for (int i = 0; i < dt.Rows.Count; i++)
{
tempSql = "INSERT INTO tblTemp (FNCL_SPLIT_REC_ID, PROJ_ID, SALES_SRC_PRC) VALUES ('"
+ dt.Rows[i]["FNCL_SPLIT_REC_ID"].ToString().Trim() + "','"
+ dt.Rows[i]["PROJ_ID"].ToString().Trim() + "','"
+ dt.Rows[i]["SALES_SRC_PRC"].ToString().Trim() + "');";
SqlCommand tempCommand = new SqlCommand(tempSql, tempDbConnection);
tempCommand.ExecuteNonQuery();
}
// There are no errors. The data just doesn't save to the database.
//===========================================================================================

epnConnection.Close();
tempDbConnection.Close();

}
catch (Exception ex)
{
epnConnection.Close();
tempDbConnection.Close();
MessageBox.Show("Error " + ex);
}
}
}
}

//+++++++++++++++++++This is what the table looks like+++++++++++++++++++++++++++++++++++++++++++++++
CREATE TABLE [dbo].[tblTemp] (
[FNCL_SPLIT_REC_ID] INT NOT NULL,
[PROJ_ID] NCHAR (10) NULL,
[SALES_SRC_PRC] MONEY NULL,
PRIMARY KEY CLUSTERED ([FNCL_SPLIT_REC_ID] ASC)


Like I said no errors come up. The data just doesn't save to the database.

Answer
"INSERT INTO tblTemp (FNCL_SPLIT_REC_ID, PROJ_ID, SALES_SRC_PRC) VALUES ("
                    + dt.Rows[i]["FNCL_SPLIT_REC_ID"].ToString().Trim() + ",'"
                    + dt.Rows[i]["PROJ_ID"].ToString().Trim() + "',"
                    + dt.Rows[i]["SALES_SRC_PRC"].ToString().Trim() + ");";

Removed the ' ' between FNCL_SPLIT_REC_ID as it is int and SALES_SRC_PRC since it is money.
